1 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
3 * gc.c (scm_gc_sweep): added a `continue' statement that have
4 fallen through the cracks in the merge. thanks to Shuji Narazaki!

7 wasn't actually needed anyway.
9 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
11 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.

29 texinfo markup and remove trailing newlines.
31 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
33 this changes the Guile GC to use cards (aka "chunklets").
34 (most of the ideas and some of the code are by Greg Harvey, though
35 the code is probably unrecognizable now. the original chunklet
36 proposal, way back, is by Dale Jordan).
38 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
39 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
40 some (most) of these are probably going to be deprecated.
42 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
44 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
45 cards and bvecs (bit-vectors).
47 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
48 account, but keeping more or less the same values as previously.
49 added some simple helper macros.
50 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
52 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
53 current_mark_space_offset, mark_space_head, get_bvec,
54 clear_mark_space): new functions and supporting variables, types
55 and macros that implement mark space management.
56 (scm_igc): clear the mark space (all of it) before beginning the
58 (scm_gc_mark): changed the tests for rogue cells, much simplified
59 throughout (no different mark bit locations to worry about now).
60 (scm_mark_locations): don't consider card header cells.
62 (scm_gc_sweep): simplified.
63 (init_heap_seg): changed to take cards into account.
65 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
67 * stime.c (scm_c_get_internal_run_time): new function, same as
68 scm_get_internal_run_time but returns a long. it's used by the GC
69 for timekeeping, since with scm_get_internal_run_time there is a
70 (extremely theoretical) possibility of consing.
71 (scm_get_internal_run_time): redefined in terms of
72 scm_c_get_internal_run_time.
74 * stime.h: added prototype for scm_c_get_internal_run_time.
76 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
77 sweep time, total marked cells, total swept cells, and number of
79 (gc_start_stats): renamed from scm_gc_start, made static, taught
80 to init the new stats.
81 (gc_end_stats): renamed from scm_gc_end, made static, taught to
82 calculate the new stats.
83 (scm_igc): don't call gc_start_stats unless we are sure that we
84 are indeed going to collect. also, added some timekeeping between
85 the mark and sweep phases.
86 (scm_gc_sweep): count number of cells we sweep as we go.
88 * gc.h: removed prototypes for scm_gc_{start,end}.
90 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
92 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
93 error for the alist rather than the sublist where the type
94 mismatch is discovered.
96 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
98 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue

125 reference manual doc on keywords.
127 * error.c (scm_error_scm): Fix texinfo syntax error in
128 docstring. (@code(~S) should be @code{~S}.)
130 * dynl.c: Remove surplus newlines from end of docstrings.
132 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
134 * eval.c (scm_eval): Backward incompatible change: Now takes an
135 environment specifier as second arg. `eval' hereby becomes R5RS
137 (scm_i_eval_x, scm_i_eval): New functions (replace
139 (scm_eval2, scm_eval_3): Deprecated.
140 (scm_top_level_lookup_closure_var): Deprecated.

163 scm_interaction_environment ().
165 * script.c (scm_shell): Pass scm_the_root_module () as second arg
168 * load.c (load): Use `scm_selected_module' to compute second arg
169 to new scm_i_eval_x; Don't call it if module system hasn't booted.
170 (scm_read_and_eval_x): Deprecated.
171 #include "modules.h".
173 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.
174 (scm_start_stack): Use scm_i_eval.
176 * strports.c: #include "modules.h".
178 * print.c (scm_simple_format): Be case-insensitive for ~A and ~S
181 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
183 The following changes are intended to ensure that struct instances
184 are freed before their vtables. It's optimized for the most
185 common case, which is freeing of struct instances.
187 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
188 (scm_structs_to_free): New variable.
189 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
192 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
194 (scm_structs_to_free, scm_struct_prehistory): Declare.
196 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
197 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
199 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
200 (scm_struct_prehistory): Install them.
202 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
204 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
206 * read.c (scm_flush_ws): Include filename in error message when it
209 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
211 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
213 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
215 * struct.c (scm_make_struct_layout, scm_make_struct,
216 scm_make_vtable_vtable): Updated documentation.
218 * print.c (scm_simple_format): Bugfix: Coerce port before using
221 2000-07-31 Gary Houston <ghouston@arglist.com>
223 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
224 (thanks to Richard Kim for the bug report).
226 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
228 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
229 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
230 using the latter is pointless.
232 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
234 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
235 'free_struct_data' to avoid confusion with stdlib's 'free'.
237 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
239 * vectors.c (scm_make_vector): Fix the initialization order of
240 the vector such that the type cell is initialized last.
242 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
244 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
245 on the struct cell to be fully initialized.
247 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
248 initialization order of the struct such that the type cell is
251 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
253 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
254 scm_assoc_remove_x): Remove only the first cell with a matching
257 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
259 * stime.c (scm_strftime): Recognize a return value of zero from
260 strftime as buffer overflow and take care to detect a valid zero
261 length result regardless. Thanks to David Barts!
263 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
265 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
266 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
267 equal (respectively) to the argument key, not all cells that are
268 eq, eqv, or equal to the first cell with the argument key. Thanks
271 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
273 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
274 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
275 SCM values appropriately.
277 * modules.c (scm_standard_eval_closure): Don't pass an inum to
278 scm_makcclo, but rather a long value.
280 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
282 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
283 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
284 Thanks to Han-Wen Nienhuys for the bug report.
286 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
288 * root.[ch] (scm_call_catching_errors): Deprecated.
290 * root.c (scm_init_root): Initialize the root smob type using the
291 standard initialization functions.
293 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
295 * eval.c (unmemocopy): Don't rely on V being a list of at least
296 one element. Thanks to Bill Schottstaedt!
298 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
300 * gc.c (scm_done_free): new.
301 expanded comments about scm_done_malloc.
303 * gc.h: added prototype for scm_done_free
305 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
307 * gc.h (scm_take_stdin): Removed.
309 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
310 scm_assert_cell_valid to allow extensions to the checking
311 functionality without need to recompile everything.
313 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
314 Added as conditionally compiled functions for the case that
315 SCM_DEBUG_CELL_ACCESSES is enabled.
317 * gc.c (debug_cells_p): Added to indicate whether compile-time
318 included cell access debugging is run-time enabled.
320 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
321 being executed. Intended to be used instead of scm_gc_heap_lock
324 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
325 instead of scm_gc_heap_lock.
327 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
329 * gc.c (scm_mark_locations): Don't mark free cells.
331 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
334 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
336 * gc.c (scm_mark_locations): Minimized some variable scopes and
337 simplified the code a bit.
339 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
341 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
342 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
343 should not be accessed via SCM_C[AD]R. Further, using dedicated
344 macros to access free cells allows all other cell accessing macros
345 to treat acesses to free cells as errors, thus enabling better
346 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
347 replace SCM_FREEP some time.
349 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
350 free_list_length, scm_check_freelist, scm_debug_newcell,
351 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
352 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
353 cell accessors when accessing free cells.
355 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
357 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
358 object as const in order to make the compiler warn about code like
359 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
362 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
363 as an address to a non-const object, since these macros are used
364 to allow direct write access to objects.
366 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
368 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
369 given hash table has no slots.
371 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
373 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
374 to react to malloc failures in a context dependent way.
376 (scm_check_freelist): No need to flush streams before abort().
378 (scm_gc_for_newcell): Try to allocate new memory in three phases:
379 grow heap if preferred, if still no memory available collect
380 garbage, if still no memory available grow heap.
382 (heap_segment_table_size): Added to always reflect the actual
383 size of the heap segment table, because scm_n_heap_segs may differ
384 from the heap segment table size.
386 (alloc_some_heap): In case of malloc failure, react according to
387 the new policy_on_error parameter (either return to caller or
388 abort immediately). Further, keep heap_segment_table_size up to
391 (scm_init_storage): Initialize heap_segment_table_size.
393 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
395 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
398 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
400 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
401 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
402 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
403 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
406 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
407 and SCM_NALLOC, but as a deprecated feature.
409 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
411 * debug.c: Added #include fluids.h.
413 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
414 primitive generics. (Thanks to Nicolas Neuss.)
416 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
418 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
419 failed attempt to get additional memory from the system.
421 (scm_gc_for_newcell): Changed the control structure to make the
422 behaviour explicit for the case that gc is not able to free any
425 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
427 * __scm.h (SCM_OUTOFRANGE): Removed.
429 * error.c (scm_wta): Removed sick dispatch code for range
430 errors. (More sick dispatches still to be removed.)
432 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
433 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
434 value is non-negative. Use scm_out_of_range to signal range
437 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
440 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
441 error reporting (now uses original input parameter to report wrong
442 type argument errors). Use SCM_OUT_OF_RANGE to report range
443 errors and SCM_WRONG_TYPE_ARG to report type errors.
445 * strings.c (scm_substring): Make range checks for negative
446 values explicit (former behaviour relied on an implicit
447 conversion from signed to unsigned). Don't use SCM_ASSERT for
450 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
451 scm_bit_count_star): Use scm_out_of_range to signal range
454 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
455 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
456 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
458 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
460 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
461 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
462 Perform all range checks based on the input value. The former way
463 of using the value that is assigned to the target variable fails
464 if the assignment to the target variable itself can change the
465 value because of type conversion.
467 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
469 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
471 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
472 doesn't yield any new cells. In theory this could happen if all
473 cells allocated with NEWCELL are either in use or conservatively
474 marked and all cluster spine cells are conservatively marked.
477 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
479 * __scm.h (SCM_NALLOC): Removed.
481 * error.c (scm_wta): Removed sick dispatch code for memory
482 errors. (More sick dispatches still to be removed.)
484 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
485 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
486 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
487 (scm_vector_set_length_x): Now using scm_memory_error to signal
490 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
492 * __scm.h: Removed some commented code and fixed some comments.
494 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
495 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
496 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
498 * async.c: Removed some commented code.
500 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
502 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
503 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
504 appropriate error signalling function.
506 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
508 * root.h (scm_first_type): Removed.
510 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
512 * gc.c (MIN_GC_YIELD): Removed.
514 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
516 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
519 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
521 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
524 (scm_init_async): Moved initialization for scm_gc_async and
525 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
528 * async.h (scm_gc_async): Not globally visible any more.
530 * gc.c (scm_gc_stats): Made callable even from within regions
533 (scm_gc_end): Eliminate the hardcoding of the marking of the
534 scm_gc_async from the gc core.
536 (scm_init_storage): Don't initialize the scm_asyncs list here.
537 This is now done in asyncs.c.
539 (scm_gc_vcell): Moved here from async.c.
541 (gc_async): Renamed from scm_gc_async, moved here from async.c
544 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
547 (mark_gc_async): New hook function for scm_after_gc_c_hook.
549 (scm_init_gc): Added initialization of scm_gc_vcell and
550 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
552 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
555 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
557 * gc.c (scm_igc): Removed commented code that once was intended
558 to unprotect struct types with no instances.
560 * root.h (scm_type_obj_list): Removed.
562 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
564 * async.c (scm_init_async): Switch to standard way of smob
567 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
569 * guile-doc-snarf.in: use cut instead of sed, that's much much
570 faster. also, don't call basename more than needed. and, to gain
571 a couple of microseconds more, don't call cat needlessly. (thanks
574 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
576 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
577 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
578 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
580 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
582 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
583 #include "libguile/fluids.h".
585 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
586 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
588 * root.h (scm_top_level_lookup_closure_var,
589 scm_system_transformer): Removed. (It's no sense in having the
590 *variable* be a "fluid".)
592 * root.c (mark_root): Removed marking of
593 s->top_level_lookup_closure_var and s->system_transformer.
595 * modules.c (scm_selected_module): the_module is now a fluid.
597 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
599 * gc.h, tags.h: Be kind to compilers which must see hash signs in
600 column 0. (Thanks to Ian Grant.)
602 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
603 the long_long type. (Thanks to Bernard Urban.)
605 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
607 * gc.c, gc.h (scm_default_init_heap_size_1,
608 scm_default_min_yield_1, scm_default_init_heap_size_2,
609 scm_default_min_yield_2, scm_default_max_segment_size): New global
610 variables. Can be customized by the application before booting
611 Guile. (We might want to be able to control these parameters
612 dynamically through the "options interface" in the future, but
613 note that that is additional functionality. Here we're giving
614 default values which the environment variables can override.)
616 * list.c (scm_cons_star): Updated comment.
618 * smob.h: Changed comments for scm_make_smob_type and
619 scm_make_smob_type_mfpe, warning that the latter might be
620 deprecated in a future release.
622 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
624 * list.[ch] (scm_cons_star/cons*): Renamed from
627 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
628 for scm_cons_star/cons*.
630 * gc.c (scm_protect_object): Updated comment.
632 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
634 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
636 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
638 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
641 * gdbint.c (gdb_print): Print warning instead of calling scm_write
642 if Guile isn't yet initialized.
644 * print.c (scm_current_pstate, scm_make_print_state): Simplified
645 tests, using the assumption that Guile has been initialized.
647 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
649 * print.c (s_scm_current_pstate): Do not segfault when the
650 print_state_pool is unitialized in `current-pstate', and better
651 verify its state before altering it in scm_make_print_state().
653 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
655 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
656 #ifdef -- it's missing on at least one platform. (thanks to
659 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
661 * list.c (list*): Added documentation from common-list.scm.
663 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
665 * gc.c (scm_unprotect_object): The reference count is guaranteed
666 to be a positive number.
668 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
670 * eval.c: Updated comment above scm_map.
672 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
674 * gc.c (scm_protect_object): Avoid looking up the object handle
676 (scm_unprotect_object): Abort if scm_unprotect_object is called on
677 an unprotected object.
679 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
681 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
684 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
686 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
688 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
689 Ditto for `tmp_size'.
690 (scm_addr_buffer_size): Changed type from int to size_t.
692 * random.c: #include <string.h>. (Needed by memcpy.)
694 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
695 indicating stdin, instead of "" and don't reset ARGC. This is a
696 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
697 it is correct, and perhaps even better.
699 2000-06-14 Gary Houston <ghouston@arglist.com>
701 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
702 defined, add SA_RESTART to the sigaction flags correctly
703 (thanks to Dale P. Smith).
705 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
707 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
709 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
710 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
712 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
714 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
716 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
717 since read and write buffers are allocated by `malloc'.
719 * Makefile.am: Removed old test code.
721 * gh_test_c.c, gh_test_repl.c: Removed.
723 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
725 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
728 * inet_aton.c (inet_aton): Cast init value for `cp'.
730 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
733 * symbols.c (scm_intern_obarray_soft,
734 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
735 in calls to scm_strhash.
737 * strports.c (st_resize_port): Substituted SCM_UCHARS for
739 (st_write): Cast argument to strncpy to char ptr.
740 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
741 (scm_strport_to_string): Cast argument to scm_makfromstr to char
744 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
745 storing in putback_buf.
746 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
748 * ioext.c (s_scm_read_line): Cast result of call to
749 scm_do_read_line to unsigned char ptr.
751 * gdbint.c (SEND_STRING): Cast argument to char pointer.
753 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
756 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
757 shouldn't use Make rules which aren't supported by most Make
759 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
760 want these dependencies recorded, since they would get bogus
761 relative paths; libguile.h is only used in gh.h and guile.c.)
762 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
763 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
764 (modinclude_HEADERS): Removed kw.h.
766 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
767 (The preprocessor might insert spaces before the identifier.)
769 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
770 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
772 * smob.h (scm_smobfuns): Removed deprecated type.
774 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
775 (Replaced by `scm_make_smob_type'.)
777 * keywords.c (scm_tc16_kw): Removed deprecated type.
778 (Replaced by scm_tc16_keyword.)
780 * kw.h: Removed deprecated header file.
782 * evalext.c (serial-map): Removed deprected alias for scm_map.
783 (Has been replaced by `map-in-order'.)
785 * ramap.c (serial-array-copy!, serial-array-map!): Removed
786 depracted aliases. (Replaced by `array-copy-in-order!' and
787 `array-map-in-order'.)
789 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
791 * gc.h (SCM_VALIDATE_CELL): Rewritten.
792 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
793 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
794 (Thanks to Han-Wen Nienhuys.)
796 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
798 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
799 write it to the temp file first and check the CPP return code.
800 (I introduced this bug earlier, and this probably caused people
801 with non-GNU C preprocessors to get empty *.x files and not to
802 have the build fail right away...).
804 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
805 -- at least my libc5-based Linux system doesn't define SIGSYS.
807 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
809 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
810 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
811 (Thanks to Bernard Urban.)
813 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
815 * modules.c (scm_system_module_env_p): Fixed detection of system
818 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
820 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
821 `program error signals' because they can't currently be handled by
824 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
826 * procs.h (SCM_SET_SUBRF): Added.
828 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
829 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
832 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
834 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
837 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
838 scm_merge_list_step): Don't take the address of SCM_CAR. Use
839 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
841 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
843 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
844 replacement for !SCM_FALSEP.
846 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
847 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
848 (scm_primitive_load), print.c (scm_simple_format), procs.c
849 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
850 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
851 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
852 (scm_string_to_obarray_symbol), throw.c (scm_catch,
853 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
854 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
855 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
856 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
858 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
860 * eval.c (scm_badformalsp): New static function.
861 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
862 (Thanks to Keisuke Nishida.)
864 The major reason for Guile's slow loading speed has been the fact
865 that a chain of Scheme level procedures has been evaluated for
866 every top-level symbol lookup during the first pass through the
869 The following is a kludge which I suggested four years ago, and
870 which I've repeatedly suggested since. Personally, I've never
871 been bothered by Guile's slow loading speed, so I thought I would
872 let someone else do it...
874 But since the new environments will be included first in
875 Guile-1.5, I thought it would make people happy to get the kludge
878 * modules.c: Added #include "libguile/vectors.h";
879 Added #include "libguile/hashtab.h";
880 Added #include "libguile/struct.h";
881 Added #include "libguile/variable.h";
882 Capture Scheme level `module-make-local-var!' to be used in the
883 standard eval closure.
884 (scm_standard_eval_closure): New primitive.
886 * modules.h (scm_standard_eval_closure): Declare.
888 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
889 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
891 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
892 standard eval closures.
894 * variable.c: Code layout fixes.
896 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
898 * Makefile.am: Added LIBS line to libpath which accidentally
899 disappeared in the change of 2000-06-01.
900 (Thanks to Dale P. Smith.)
902 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
904 * scmsigs.c (scm_segfault): Removed. (Was probably added by
905 mistake since it is not mentioned in ChangeLog.)
907 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
908 avoid compiler warnings in gcc. (Does this work for other
911 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
913 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
915 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
916 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
917 the address of these expressions since they use SCM_VALIDATE_CELL.
918 (Thanks to Bernard Urban.)
920 * dynl.c: Changed #include <ltdl.h> --> #include
921 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
923 2000-06-01 Craig Brozefsky <craig@red-bean.com>
925 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
926 from GUILE-VERSION definition of LIBGUILE version. Added to
927 libpath.h definitions for guileversion and libguileversion which
928 both get their values from GUILE-VERSION definition.
930 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
932 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
933 file: Code using numbers should not be required to include
936 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
938 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
939 mit-pthreads.c, mit-pthreads.h: Deleted.
941 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
942 references to deleted files and fsu/mit thread support in
945 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
947 * hooks.c (symbol_name, scm_create_hook): Restored the original
948 behaviour of scm_create_hook. Changing it was bad as Carl
949 R. Witty has pointed out.
951 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
954 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
956 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
957 soon not be done by scm_create_hook any longer.
959 * hooks.c (make_hook, print_hook, scm_create_hook,
960 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
961 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
962 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
963 longer have names. As an intermediate solution, the name
964 predicate is emulated via object properties, but use of this
965 feature is deprecated.
967 * hooks.h (scm_free_hook): Removed, as it is never defined.
969 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
971 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
972 Un-deprecated since otherwise user code can't determine whether a
973 number fits into an inum any longer. The names should be changed
976 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
978 * tags.h (SCM_UNPACK_CAR): Deprecated.
980 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
982 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
983 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
984 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
985 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
986 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
987 SCM_{SET}?C[AD]R unless they are known to be cons cells.
989 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
990 init_heap_seg): Remove unused struct member variable 'valid'.
992 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
994 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
995 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
996 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
997 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
998 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
1001 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1003 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
1004 (scm_macro_type), objects.c (scm_class_of), options.c
1005 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
1006 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
1008 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1010 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
1011 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
1013 * eval.c (scm_force): Add documentation.
1015 * eval.c (scm_force, scm_cons_source): Don't access cells via
1016 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1018 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1020 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1021 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1023 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1024 nosve #endif conditionally compiled code.
1026 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1028 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1030 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1032 * guile-doc-snarf.in: put the preprocessed file through sed to
1033 trim all lines to 1024 chars. I hope it doesn't break anybody's
1034 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1035 isn't wrapped around but actually chopped off. this seemed to me
1036 safe because the current snarfer doesn't understand multi-line
1037 cookies anyway. in the long term, it would be nice not to depend
1038 on AWK for anything.)
1040 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1041 the previous change to this macros, after deciding to torture the
1044 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1046 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1047 the yucky, ugly and nasty conditional compilation back. sorry,
1048 but it was either that or requiring GAWK to build Guile.
1049 (lots of places): removed the code that implemented the old GC
1052 * init.c (scm_boot_guile_1): removed the code conditioned on
1053 !GUILE_NEW_GC_SCHEME.
1055 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1057 * gc.c (scm_protect_object, scm_unprotect_object): change the
1058 implementation to more efficient (at least in the time complexity
1059 sense). the calls should now also be thread-safe -- I suspect
1060 that people expect them to be. (thanks to Han-Wen Nienhuys)
1061 (lots of places): removed the code that implemented the old GC
1064 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1065 SCM_REALLOW_INTS before return. I really wonder about the
1066 possible interactions between hashtables, threads & GC. it
1067 doesn't look healthy at all.
1069 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1071 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1074 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1076 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1077 debug option to verify all accesses to cells actually access
1078 objects on the heap.
1080 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1081 SCM_DEBUG_CELL_ACCESSES is set to 1.
1083 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1084 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1087 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1089 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
1090 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.

1111 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1112 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1113 the actual arguments in the list, but rather the rest argument as
1114 a list of arguments.
1116 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1118 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c

1126 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1127 (scm_dynamic_link): Removed possibility to pass flags to
1128 scm_dynamic_link, as it had no effect anyway.
1130 * filesys.c (scm_fcntl): Made single optional rest argument into
1131 a standard optional argument.
1133 * hooks.c (scm_run_hook): A list of rest arguments is never
1136 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1137 strings.c (scm_string_append): Don't perform half-hearted checks
1138 to see whether the rest argument forms a proper list any more, use
1139 SCM_VALIDATE_REST_ARGUMENTS instead.
1141 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1144 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1145 Simplify verification of rest argument.
1147 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c

1153 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
1154 rest argument into a standard mandatory argument.
1156 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1158 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1159 Keisuke Nishida for the suggestion.) Added debug option
1160 SCM_DEBUG_REST_ARGUMENTS.
1162 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1163 same length. Also, removed redundant parameter checks.

1167 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
1169 * __scm.h: Improved explanation of giving options to make.
1171 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1172 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1173 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1174 corresponding declaration and comment to __scm.h.

1177 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1178 SCM_INUM): Removed conditionally compiled code for Turbo C.
1180 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1181 That check can be assumed to be redundant except for very rare
1182 conditions that actually indicate broken heap data.
1184 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1186 * numbers.c (scm_logcount, scm_integer_length): Reordered
1189 2000-05-15 Gary Houston <ghouston@arglist.com>
1191 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1192 string. append a "0" to the zone for TZ.
1194 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1196 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1199 (scm_bit_extract): Fixed handling of bignums.
1201 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>

1214 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
1215 scm_output_port_p), print.c (scm_get_print_state), validate.h
1216 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1217 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1218 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1220 2000-05-14 Gary Houston <ghouston@arglist.com>
1222 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1223 TZ environment variable so that the %Z format returns the zone
1224 from the input vector instead of the system default.
1226 from Keisuke Nishida:
1227 * fports.c (scm_setvbuf): minor docstring fix.
1228 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1230 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1232 * __scm.h: Added new section for debugging options.
1234 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1235 help developers to get rid of references to deprecated code.
1237 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1238 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1239 as part of the interface and are marked as deprecated in the
1242 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1243 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1246 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1247 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1248 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1250 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1252 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1253 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1254 of two scm_bits_t values instead of two SCM values, because it is
1255 legal for cell entries to hold values that are not scheme objects.
1257 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1258 Use SCM_SETC[AD]R to modify contents of pairs.
1260 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1262 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1264 (scm_abs, scm_magnitude): Make these two independent of each
1265 other. scm_abs now reports an error if given a complex argument.
1267 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1268 SCM_REALPART if the object is known to be real.
1270 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1273 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1275 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>

1281 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1282 ramap_rp, scm_array_map_x), random.c (vector_scale,
1283 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1284 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1285 the object is known to be real. Use SCM_COMPLEXP instead of
1286 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1289 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1291 * numbers.c: No need to include unif.h.
1293 (IS_INF): Returned to old test for now: x == x + 1 will not work
1294 for large numbers due to rounding errors.
1295 Thanks to Kalle Olavi Niemitalo.
1297 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1299 * numbers.c (scm_divbigdig): Removed outdated comment.
1301 (scm_number_to_string, scm_string_to_number, scm_number_p,
1302 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1303 scm_geq_p, scm_make_rectangular, scm_make_polar,
1304 scm_inexact_to_exact): Added comments.
1306 (add1, scm_init_numbers): Removed add1.
1308 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1310 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1311 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1314 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1315 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1318 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1320 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1321 SIGILL and SIGBUS signals. These signals are not continuable and
1322 must be handled for real right away.
1324 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1326 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1327 scm_real_part, scm_imag_part, scm_magnitude,
1328 scm_inexact_to_exact): Reordered dispatch sequence.
1330 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1332 * feature.c: No need to include "libguile/smob.h"
1334 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1335 Removed variable 'scm_loc_features' as a pointer to the SCM value
1336 holding the features list. Using variable 'features' instead,
1337 which holds the interned pair. Thus, SCM_SETCDR can be used
1338 instead of pointer trickery.
1340 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1342 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1343 cell is not known to be a valid pair.
1345 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1347 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1348 ASRTSYNTAX. Using SCM_ASSYNT instead.
1350 (scm_m_body): Don't create a redundant cons cell.
1352 (scm_m_do): Removed redundant test 'bodycheck'.
1354 (bodycheck): Removed.
1356 * stacks.c (stack_depth, read_frame, read_frames): Removed
1357 redundant calculation of size, minimized some variable scopes.
1359 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1361 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1362 long as a cell is not known to be a valid pair.
1364 (scm_pair_p): Eliminated redundant SCM_IMP test.
1366 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1368 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1369 scm_deval_args): Eliminated redundant SCM_IMP tests.
1371 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1372 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1373 scm_make_doubly_weak_hash_table): Fixed critical sections.
1374 Thanks to Keisuke Nishida.
1376 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1378 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1379 Fixed some goto-related initialization bugs (introduced by me).
1381 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1383 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1385 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1387 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1390 (SET_DYNL_HANDLE): Added.
1392 (scm_dynamic_object_p): Simplified.
1394 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1395 better error message when accessing unlinked dynamic objects.
1396 Eliminated call to get_dynl_obj.
1398 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1400 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1401 be an array of function pointers instead of being a pointer to an
1402 array returning function. Thanks to Kalle Olavi Niemitalo!
1404 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1406 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1407 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1408 indicate that a division has a remainder, return SCM_UNDEFINED
1409 instead. It is improbable that anyone actually used these
1410 functions outside of numbers.c. For this reason and due to the
1411 change in behaviour the functions are static now. Thus, if
1412 surprisingly there are users of these functions they will at least
1415 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1416 that already have a clean dispatch order. Note: SCM_BIGDIG is
1419 * numbers.c (scm_inexact_p): Simplified.
1421 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1422 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1423 sequence, thereby fixing some comparisons of SCM values with
1426 * numbers.c (scm_divide): Division by zero of inums leads to an
1427 error now. (Formerly, an infinite number was returned.)
1429 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1430 if a division has a remainder.
1432 2000-05-02 Gary Houston <ghouston@arglist.com>
1434 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1436 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1438 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1439 sequence, thereby fixing some comparisons of SCM values with
1442 * numbers.h (scm_makdbl): Mark as deprecated at the point of
1445 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
1446 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,

1454 call to scm_makdbl with a call to scm_make_real or
1455 scm_make_complex, depending on whether the imaginary part is known
1458 2000-05-01 Gary Houston <ghouston@arglist.com>
1460 * scmsigs.c: fix the definition of orig_handlers for the case
1461 that HAVE_SIGACTION is not defined (thanks to
1462 Kalle Olavi Niemitalo).
1464 * Makefile.am: remove include_HEADERS (was libguile.h)
1465 libguile.h: moved to top level directory.
1467 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1469 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1472 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
1473 scm_logxor): Reordered dispatch sequence, thereby fixing some
1474 comparisons of SCM values with integer constants.
1476 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
1479 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1481 * numbers.c (scm_quotient, scm_remainder): Removed code that was
1482 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
1483 occur anywhere else throughout guile.
1485 * numbers.c (scm_quotient): Fixed parameter number in error
1488 * numbers.c (scm_remainder): Reordered dispatch sequence.
1490 2000-04-25 Gary Houston <ghouston@arglist.com>

1498 (suggested by Jost Boekemeier).
1500 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1502 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
1505 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1506 scm_dsubr, scm_init_iprocs): Removed.
1508 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1509 directly instead of casting a cell to a C struct.
1511 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1513 Better modularization of GC extensions through new C level GC
1516 * weaks.c (scm_weaks_prehistory): New function: Add

1525 * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
1528 * guardians.c (scm_guardian_gc_init): Turned into a hook function
1529 and added to scm_before_mark_c_hook.
1530 (scm_guardian_zombify): Turned into a hook function and added to
1531 scm_before_sweep_c_hook.
1533 * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.

1536 * gc.h: Added #include "libguile/hooks.h".
1538 * gc.c: Removed #include "libguile/guardians.h".
1539 (scm_before_gc_c_hook, scm_before_mark_c_hook,
1540 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
1541 scm_after_gc_c_hook): New C level hooks.
1542 (scm_after_gc_hook): New Scheme level hook.
1543 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
1544 (scm_igc): Moved initialization of scm_weak_vectors and the call
1545 to scm_guardian_gc_init to respective module.

1571 the root build directory.
1573 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1574 instead of SCM_ASSERT (0, ...). (Some compilers will complain
1575 about control reaching end of function otherwise, and, besides,
1576 the new code is not less clear.)

1887 * async.h: kill the scm_async_t struct. having a heap cell

1959 separate loop after processing all the currently known live
1960 guardians, so as to not introduce order dependencies (thanks to
1961 Gary Houston). note that the order problems are still there if
1962 some guardians are themselves zombies, but that's a sick case that
1963 I'm not going to worry about.
1964 also, make another outer loop to process zombified

2077 access raw cell data with SCM_{SET_}?CELL_WORD_1.
2079 * debug.c (scm_make_debugobj): Don't use SCM_SETCAR to set types.
2081 * debug.c (scm_make_memoized), dynl.c (scm_dynamic_link): Smob
2082 data is of type scm_bits_t.
2084 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2086 * gdbint.c (gdb_maybe_valid_type_p), guardians.c (TCONC_EMPTYP,
2087 scm_guardian_zombify): Use SCM_EQ_P to compare SCM values.
2089 * guardians.c (GUARDIAN): Use SCM_CELL_WORD_1 for raw data.
2091 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2093 * ports.h (scm_port): Change type of stream member to scm_bits_t.
2095 * gdbint.c (unmark_port, remark_port), ports.c (scm_markstream),
2096 strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
2097 sf_write, sf_fill_input, sf_close, scm_make_soft_port): Since
2098 streams are now of type scm_bits_t, SCM streams have to be
2101 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
2104 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2106 * coop-defs.h (struct coop_t): Added `sto'-field again because of
2107 binary compatibility---let's remove it next time we alter some
2110 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
2111 coop_mother, coop_child): New variables.
2112 (mother): New function.
2113 (coop_create): New thread spawning mechanism which uses a "mother
2114 thread". The "dummy" pthreads aren't healthy enough to give birth
2115 to new threads since Linux threads thinks they are asleep.
2117 * coop-defs.h (struct coop_t): Removed dummy_mutex.
2119 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
2120 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
2122 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2124 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
2125 (scm_internal_dynamic_wind): Smob data is always of type
2128 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
2129 Access the locking information in cell entry 0 with
2130 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
2132 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
2135 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
2137 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
2138 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
2140 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2142 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
2143 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
2144 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
2145 Don't use C operators == and != to compare SCM values, use
2148 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
2149 SCM value is equal to #t or #f.
2151 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
2152 cell type entry of non immediate objects of unknown type. Use
2153 SCM_CELL_TYPE instead.
2155 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
2156 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
2157 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
2158 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
2161 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
2164 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2166 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
2167 scm_make_mutex, scm_make_condition_variable): Cast data to
2168 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
2170 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2172 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2174 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
2175 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
2176 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
2178 Note that this implies that smob data has always to be passed as
2179 values of type scm_bits_t.
2181 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2183 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
2184 for scm_tc16_thread. As the current COOP threads are written, GC
2185 is not supposed to manage storage for threads.
2187 * error.c (scm_error): Don't try to throw an error if
2188 scm_gc_heap_lock is true.
2190 * coop.c (coop_finish): New function. Called at exit.
2191 (coop_aborthelp): Free thread structures when threads die.
2192 Finished LinuxThreads compatibility support => COOP threads now
2193 mesh with LinuxThreads.
2195 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
2196 Changed SETCDR --> SET_CELL_WORD_1.
2198 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
2201 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2203 * boolean.h (SCM_TRUE_P): New macro.
2205 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
2206 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2208 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2210 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2211 access continuation data.
2213 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2215 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2216 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2219 * continuations.c (scm_make_cont), init.c (start_stack),
2220 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2223 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2225 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2226 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2228 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2229 to access the char * field of strings and symbols.
2231 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2233 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
2234 the type entry of a new cell. Added a comment about things to
2235 remember when updating the list of free cells.
2237 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2240 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2242 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2243 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2244 with strict type checking enabled these macros will only work if
2245 given valid SCM parameters.
2247 (SCM_GCCDR): Moved to tags.h.
2249 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2251 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2253 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2255 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2256 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2257 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2258 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2259 SCM_NEWCELL2): Moved to gc.h.
2261 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2262 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2263 be changed, though, since the macros are not only pair related.
2267 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2268 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2269 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2270 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2271 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2272 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2275 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2277 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2278 activates strict compile time type checking for variables of
2280 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2281 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2282 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2284 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2286 * tags.h (SCM_POINTERS_MUNGED): Removed.
2288 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2289 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2291 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2293 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2294 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2295 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2297 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2299 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2300 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2302 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2304 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2306 Defining SCM as void * introduces problems which haven't been
2307 handled yet. Developers who work with these issues can enable it
2308 in their working copies.
2310 Disabling this definition exposes a set of newly introduced and
2311 older misuses of types which causes warning messages during
2312 compilation. We'll fix this successively.
2314 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2315 in order to obtain a value of type SCM.
2316 (scm_cellp): Updated with new changes to scm_mark_locations.
2318 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2320 * continuations.c (scm_make_cont): Removed cast of size_t into
2323 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2325 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2327 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2328 shifting, not constant. Thanks to Dale P. Smith.
2330 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2331 for being less than zero. Decode it to a C value first. Again,
2334 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2336 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2337 non scheme values. If raw data is stored in SCM variables, it has
2338 to be accessed using SCM_UNPACK until a better solution is found.
2340 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2342 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2343 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2345 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2347 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2349 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2351 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2353 * async.c, __scm.h: Removed lots of the old async click logic. It
2354 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2355 __scm.h. Let's try this out and dump the old code after the
2356 threads reorganization.
2357 (set-tick-rate, set-switch-rate): Conditionally removed.
2359 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2361 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2362 made SCM values into pointers. This turned an arithmetic
2363 computation of the address of the vcell into a pointer-arithmetic
2364 one, thereby screwing up marking of structs.
2365 Bugfix 2: Removed incompletely introduced loop variable `j' used
2366 when protecting the tail array of a struct.
2368 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2370 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2372 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2374 * symbols.h, symbols.c (scm_strhash): Declare the string
2375 parameter as constant, since it is not modified.
2377 * symbols.c (scm_intern_obarray_soft,
2378 scm_sysintern0_no_module_lookup): Can now pass constant strings
2379 to scm_strhash without need for casting.
2381 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2383 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2384 values to pointers. Use SCM2PTR instead.
2386 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2388 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2389 results of SCM_INUM.
2391 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2393 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2394 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2395 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2397 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2398 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2399 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2400 gc_trigger, adjust_gc_trigger.
2402 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2404 (SCM_MAX): New macro.
2405 (scm_freelist_t): New field: collected_1. Previous amount of
2407 (gc_sweep_freelist_finish): Trigger based on two last values of
2408 freelist->collected to avoid unnecessary allocation due to
2410 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2411 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2412 without extra heap allocation.
2414 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2416 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2417 already be a C value. No need to unpack it.
2419 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2420 if we know it fits into an inum.
2422 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2423 field of long values. In contrast, SCM_VELTS accesses a field of
2426 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2428 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2430 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2431 make better judgements.
2432 (gc_sweep_freelist_finish): Inserted explanation of use of
2435 * print.h, stacks.h, options.c, options.h: Changed C++
2438 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2440 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2442 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2443 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2444 SCM_UNPACK / SCM2PTR correctly.
2446 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2448 * gc.c (adjust_gc_trigger): Improved documentation.
2449 (alloc_some_heap): Since gc_trigger is used against
2450 freelist->collected, this is the value which should be used to
2451 predict minimum growth.
2453 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2455 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2456 Thien-Thi Nguyen for the patch.)
2458 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2460 * numbers.c (scm_ash): Fixed typing problems with the second
2461 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2462 for indicating the problem.)
2464 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2466 * gc.c, gc.h (scm_gc_yield): New variable.
2467 (adjust_gc_trigger): Use scm_gc_yield.
2468 (alloc_some_heap): Use scm_gc_yield instead of
2469 scm_gc_cells_collected.
2471 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2473 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2475 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2476 trigger adjustmeant: Take yield (freed cells) for all freelists
2478 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2479 to 50000 cell heap with 45% trigger.
2480 (scm_gc_cells_collected): Reintroduced.
2481 (SCM_HEAP_SIZE): New macro.
2482 (scm_gc_sweep): Reintroduced correct computation of
2483 scm_cells_allocated.
2484 (scm_freelist_t): Corrected commentary for field `cluster_size':
2485 Clustersize counts objects, not cells; New member
2486 `clusters_allocated'.
2488 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2490 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2493 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2495 * threads.h: Added #include "libguile/throw.h". (Thanks to
2498 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2500 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2501 names, anyone got any better ones?)
2503 * gc.h: (typedef struct scm_freelist_t) remove from here.
2505 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2506 parameter (the span).
2507 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2508 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2509 business being externally visible.
2510 (typedef struct scm_heap_seg_data_t) renamed from
2511 scm_heap_seg_data, to be style-compliant.
2512 (scm_mark_locations) if the possible pointer points to a
2513 double-cell, check that it's properly aligned.
2514 (init_heap_seg) align double-cells properly, work with the
2515 assumption that the segment size divides cleanly by cluster size.
2516 (round_to_cluster_size) new function.
2517 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2518 to satisfy the new init_heap_seg invariant.

2571 * Makefile.am arbiters.c backtrace.c debug.c dynl.c dynwind.c
2572 error.c filesys.c fluids.c gc.c gsubr.c guardians.c keywords.c
2573 libguile.h mallocs.c numbers.c print.c random.c read.c root.c
2574 srcprop.c stackchk.c struct.c threads.c throw.c variable.c:
2575 Removed reference to genio.h
2577 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2579 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2580 Cluster sizes are now independent of GC trigger values.
2581 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2582 A negative integer gives fraction of total heap size in percent.
2583 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2585 * init.c (scm_boot_guile_1): Introduced new variable
2586 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2587 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2588 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2590 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2592 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2593 freeing of segment work with the new GC scheme. (Thanks to
2594 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2595 the default, but I'll let this change stay in CVS Guile since this
2596 code is not expected to contain serious bugs.
2598 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2600 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2602 (scm_free_list_length): New procedure (GUILE_DEBUG).
2603 Fixed a small but serious bug introduced by the previous change.
2605 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2606 loop and declare as register.
2608 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2611 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2613 * fluids.c: Docstring patch from Keisuke Nishida. Some
2614 reindentation, too, and a couple formals renamed. Should
2615 fluid-set! return UNSPECIFIED instead of a value?
2617 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2619 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2620 generate the latter from the concrete listing of the former. Then
2621 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2622 *.doc, so that rebuilding it works.
2624 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2626 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2628 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2629 with nothing and \n, respectively. Thanks Keisuke Nishida for
2630 noticing this problem.
2632 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2634 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2635 new way of allocating heap. It makes Guile fast, but still
2638 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2639 allocating heap. The basic idea is to trigger GC every Nth
2640 allocated cell and grow heap when free list runs out. The scheme
2641 has been extended so that GC isn't triggered until all remaining
2642 cells are used. The implementation is also prepared for
2643 development in the direction of POSIX threads.
2645 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2646 SCM_EXPHEAP should return half of the heap size.
2648 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2650 The following change to init.c is only enabled if Guile was
2651 configured with --enable-guile-debug.
2653 * init.c (scm_i_getenv_int): New function.
2654 (scm_boot_guile_1): Use the environment variables
2655 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2656 they exist. (This may be replaced by a Scheme level mechanism in
2659 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2660 scm_assoc. (Thanks to Keisuke Nishida.)
2662 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2664 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2665 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2667 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2669 * init.c (scm_boot_guile_1): Use same initial segment size for
2670 1-word and 2-word segments. Having the smaller size causes Guile
2671 to GC too often. Obviously something needs to be done to allow
2672 for a smaller 2-word segment without this to happen. (The amount
2673 of heap for each type should be automatically adapted to the
2674 application somehow.)
2676 [Almost all of these changes should be documented in the NEWS
2679 * gc.h (scm_freelist_t): New type.
2681 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2683 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2684 all of Guile basics fits into one segment and there suitable room
2686 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2688 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2689 Freelists now contains information about object span, cells
2690 collected and amount of cells in heap segments belonging to the
2692 (scm_heap_size, scm_gc_cells_collected): Removed.
2694 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2696 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2699 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2700 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2701 rewrite of handling of real and complex numbers.
2702 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2703 removed along with the support for floats. (Float vectors are
2706 * tags.h (scm_tcs_bignums): Removed.
2707 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2708 Use SCM_BIGSIGN(x) to test for sign!
2709 (scm_tc16_big): The new bignum type.
2710 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2712 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2713 (scm_makdbl): Deprecated.
2714 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2715 (SCM_SINGP): Deprecated.
2717 (SCM_INEXP, SCM_CPLXP): Deprecated.
2718 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2719 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2720 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2721 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2722 for doubles and complex numbers.
2723 (SCM_REAL_VALUE): New selector for doubles.
2724 (scm_double_t, scm_complex_t): New types.
2727 * numbers.c (scm_floprint, scm_floequal): Removed.
2728 (scm_print_real, scm_print_complex, scm_real_equalp,
2729 scm_complex_equalp): New functions.
2731 * unif.c (scm_makflo): Removed.
2733 * smob.h (SCM_SMOB_PREDICATE): New macro.
2734 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2735 SCM_RETURN_NEWSMOB3): New macros.
2737 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2739 The following changes implement primitive support for double cells
2740 (i.e. four-word cells) and change the representation of some
2741 things to multi-cells instead of cons+malloc. (Applied and
2744 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2745 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2746 multi-cell access macros (used by the ones below).
2747 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2750 * gc.c (scm_freelist2): multi-cell freelists.
2751 (inner_map_free_list): map_free_list, parameterized on ncells.
2752 "nn cells in segment mm" was misleading for ncells > 1; changed to
2753 "objects". still print cells too, though.
2754 (scm_map_free_list): rewritten using inner_map_free_list.
2755 (scm_check_freelist): get freelist as parameter, since now we have
2757 (scm_debug_newcell2): multi-cell variants of
2759 (scm_gc_for_newcell): take ncells and freelist pointer as
2761 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2763 (scm_gc_sweep): don't free the float data, since it's not malloced
2765 (init_heap_seg): didn't understand what n_new_objects stood for,
2766 so changed to n_new_cells.
2767 (make_initial_segment): new function, makes an initial segment
2768 according to given ncells.
2769 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2771 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2772 {DEFER,ALLOW}_INTS thing removed.
2774 * numbers.h (struct scm_dbl): changed to represent a double cell,
2775 with the number in the second half.
2777 * dynwind.c: changed the wind-guards representation to double
2780 * procs.c, procs.h: changed the procedure-with-setter representation
2783 * async.c, async.h: made async representation a double cell.
2785 * dynl.c: made dynamic_obj representation a double cell.
2787 2000-03-13 Gary Houston <ghouston@arglist.com>
2789 * ports.c (flush_void_port): renamed to flush_port_default.
2790 (end_input_void_port): renamed to end_input_default.
2792 * init.c (scm_standard_stream_to_port): create a void port instead
2793 of opening /dev/null if the standard file descriptors are bad.
2794 advantages: no portability problems, doesn't waste a file descriptor,
2795 simplifies the code (thanks to Marius for the idea).
2797 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2799 * void ports: make reading from a void port give EOF instead of
2801 * ports.c (s_scm_sys_make_void_port): modified docstring.
2802 (fill_input_void_port): new proc.
2803 (scm_init_ports): set up fill_input_void_port.
2804 * ports.c (scm_port_non_buffer): new proc.
2805 (scm_void_port): call scm_port_non_buffer.
2807 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2808 which was incorrectly appended.
2810 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2812 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2813 that we can't use autoconf for this. Autoconf itself relies on
2814 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2817 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2819 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2820 EXTRA_libguile_la_SOURCES.
2822 * iselect.h: Always declare scm_internal_select.
2824 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2825 end. Also let scm_internal_select be a real function also when
2828 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2830 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2832 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2833 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2834 and kind of an experiment: Will this cause problems?)
2836 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2838 * Makefile.am: Added *.doc to DISTCLEANFILES.
2840 2000-03-12 Gary Houston <ghouston@arglist.com>
2842 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2843 the fdes is valid before doing anything else. check that
2844 the file descriptor supports the modes required.
2845 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2846 work: just use the default buffer size.
2848 * throw.c: change an outdated comment about scm_internal_catch
2849 BODY: it doesn't take a jumpbuf arg.
2851 * init.c (scm_standard_stream_to_port): install a handler in case
2852 scm_fdes_to_port throws an error. don't check here whether the
2853 file descriptor is valid, since scm_fdes_to_port will do that.
2854 set the revealed count depending on whether the port got the
2855 standard file descriptor.
2856 (stream_body_data): new type.
2857 (stream_body, stream_handler): new procs.
2859 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2861 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2862 Renamed from SCMWORD.
2864 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2866 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2868 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2869 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
2870 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
2871 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
2872 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
2873 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
2874 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2875 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2876 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2878 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2880 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2881 tags.h: Fixed copyright notices.
2883 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2885 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2887 * init.c (scm_standard_stream_to_port): Check whether the file
2888 descriptor is valid and substitute "/dev/null" when not.
2890 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2892 * coop-defs.h (struct timespec): Conditionally defined.
2894 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2897 * readline.c (match_paren): Bugfix: First arg to select is not
2898 number of descriptors but the number of the highest descriptor +
2901 This is a preliminary attempt at a cleanup of the threads support
2902 code. It moves things to better places, makes arguments more
2903 consistent with the POSIX API (which is used in GNOME's glib), and
2904 adds new functionality.
2906 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2908 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2910 (scm_cond_init): Changed definition to
2911 coop_new_condition_variable_init.
2913 * coop.c: #include <errno.h>
2914 (coop_timeout_qinsert): Moved here from iselect.c
2915 (coop_new_mutex_init, coop_new_condition_variable_init): New
2916 functions. The strange names are temporary. Use scm_mutex_init
2917 and scm_cond_init instead.
2918 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2919 is ANSI C, but should we check for individual error codes in
2921 (coop_condition_variable_timed_wait_mutex): New function.
2922 (coop_key_create, coop_setspecific, coop_getspecific,
2923 coop_key_delete): New functions.
2925 * iselect.c (coop_timout_qinsert): Moved to coop.c
2927 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2929 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2930 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2932 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2935 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2936 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2937 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2939 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2942 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2944 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2945 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2946 logical functions from SCM.
2948 (logand, logior, logxor, logtest, logbit?): Extended scheme
2949 logical functions to use bignums from SCM.
2951 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2952 lognot from using bignums.
2954 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2956 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2957 eliminating some warnings.
2959 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2962 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2963 what the scm_return_first* functions do.
2965 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2967 * libguile/*.[ch]: make a distinction between SCM as a generic
2968 name for a Scheme object (now a void*), and SCM as 32 bit word for
2969 storing tags and immediates (now a long int). Introduced
2970 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2971 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2973 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
2975 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2976 various logXXX primitives. Thanks Eric Moore!
2978 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2980 * run-test, remaining-docs-needed: Added these scripts. The
2981 second one is only temporary until the docstring additions are
2982 complete. run-test may best live on, but is here mostly for
2983 convenience and awareness for now.
2985 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2987 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2989 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2990 displaying the expected type. Use SCM_LISTn in a couple places
2991 instead of scm_cons-ing by hand.
2993 * __scm.h: Added SCM_ASSERT_TYPE macro.
2995 * validate.h, scm_validate.h: Added the former, as a renamed
2996 version of the latter with SCM_ASSERT_TYPE used in
2997 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2999 * Makefile.am: Rename scm_validate.h to validate.h.
3001 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
3002 prefix was superfluous).
3004 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3006 * hashtab.c: Improved documentation for lots of functions. Added
3007 handwritten docs for `hash-fold'.
3009 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3011 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3013 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3015 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3016 added append docs from R4RS.
3018 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3019 Thanks Dirk Hermann!
3021 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3022 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3024 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
3025 Drop use of SCM_P for function prototypes... assume an ANSI C
3026 compiler. Thanks Dirk Hermann!
3028 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3030 * ports.c: Made `set-port-column!' and `set-port-line!' each
3031 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3032 that caused a seg fault. Also fixed `set-port-column!'s
3033 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3035 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3037 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3038 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3039 strings.c, variable.c: Added lots of documentation, cleaned up
3040 some existing documentation. Occasionally changed formal params
3041 to match docs. Also folded an #ifdef into the inners of a
3042 primitive instead of having two copies of the primitive
3043 (`get-internal-real-time', from stime.c)
3045 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3047 * ports.c: Added docs for primitives missing them. Written by
3050 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3052 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3053 just execing guile-func-name-check. Thanks Michael Livshin!
3055 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3057 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3058 dead code. Patch from Michael Livshin.
3060 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3063 2000-02-09 Gary Houston <ghouston@arglist.com>
3065 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3066 current-output-port unbuffered by default. this is less confusing
3067 for interactive use. it was line-buffered because of a
3068 performance problem with unbuffered ports, but I think it will be
3071 2000-02-08 Gary Houston <ghouston@arglist.com>
3073 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3076 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3077 HAVE_TZNAME are defined, use an empty string instead of giving two
3078 spurious compile-time errors.
3080 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3082 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3085 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3087 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3089 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3091 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3092 (which is GNU GPL'd).
3094 2000-01-31 Gary Houston <ghouston@arglist.com>
3096 * strings.h: don't use SCM_P. don't include <string.h>.
3097 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3099 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3100 previously it defaulted to zero for no good reason that I can see.
3101 use a local variable for SCM_INUM (k). replace
3102 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3104 (scm_makfromstr): cosmetic changes.
3106 (scm_string): Accept only chars in the list, not strings, for
3107 conformance to R5RS (particularly for list->string, which is
3108 supposed to be the inverse of string->list.) remove
3109 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3110 scm_makstr handles the cell allocation. when reporting wrong-type
3111 arg, don't report the position as 1.
3113 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3115 2000-01-29 Gary Houston <ghouston@arglist.com>
3117 * posix.c (scm_pipe): rewrote the docstring.
3119 * filesys.c (scm_select, retrieve_select_type, get_element,
3120 fill_select_type, set_element): modified so that Scheme
3121 "select" tests port buffers for the ability to provide input
3122 or accept output. Previously only the underlying file descriptors
3123 were checked. Rewrote the docstring.
3125 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3127 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3128 from Gregg Reynolds. Thanks Gregg!
3130 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3132 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3133 adding "x" prefix to the line so that guile-func-name-check
3134 doesn't complain unnecessarily.
3136 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3138 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3139 for maintainability.
3141 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3144 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3146 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3147 suggests removing tag.c altogether (and using a new `class-of'
3150 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3151 a bit by me to use FOO instead of @var{foo} and to have the
3152 summary come before preconditions on input. Also dropped trailing
3155 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3156 function with scm_make_subr_opt w/ last arg of 0 so it is not
3157 visible at the Scheme level. Mikael says that this is the right
3158 thing because the first arg to the proc is the guts of a compiled
3159 closure and shouldn't be exposed to the Scheme level.
3161 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3163 * sort.c: typo in comment fixed.
3165 * keywords.c: Added documentation.
3167 * guardians.c: Added documentation (could be better).
3169 * gc.c: Added docs for gc-set-debug-check-freelist.
3171 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3173 * boolean.c: Added docs for `not', `boolean?' (by hand).
3175 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3177 * random.c: Added documentation, from SLIB page:
3178 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3180 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3182 * variable.c, version.c: Added documentation, written by hand
3183 since I could not find anything already written that was
3186 2000-01-23 Gary Houston <ghouston@arglist.com>
3188 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3189 not defined (thanks to Richard Y. Kim).
3191 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3193 * Makefile.in: Removed, this is auto-generated.
3195 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3197 * list.c: Put some variable initialization code at the point of
3198 declaration; Added a comment for list*; Formatting changes.
3200 * load.c: use SCM_NNULLP to make sure the end of a list is not
3203 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3205 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3206 result of scm_list_p as C boolean.
3207 (scm_display_error_message, scm_set_print_params_x): Use new
3208 validation macros. (Thanks to Dirk Herrmann.)
3210 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3212 * strports.c (st_end_input): Inserted parenthesis to get operator
3215 * list.h (scm_init_list): Removed SCM_P around prototypes.
3217 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3218 filesys.c, posix.c: Converted docstrings to ANSI C format and
3219 escaped " occurring inside string literals.
3221 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3223 * posix.c (scm_mknod): Escape " occuring inside docstring.
3225 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3227 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3228 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3229 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
3230 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
3231 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
3232 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
3233 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3234 weaks.c: Converted docstrings to ANSI C format.
3236 * filesys.c (scm_chmod), simpos.c (scm_system), version
3237 (scm_version), vports (scm_make_soft_port): Escape " occuring
3240 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3242 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3243 SCM_VALIDATE_LONG_COPY
3245 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3246 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3247 couple of formal arguments (and fix their uses) to make arguments
3248 match the documentation.
3250 2000-01-14 <mstachow@alum.mit.edu>
3252 * Makefile.am: Augment path when running guile-doc-snarf so
3253 guile-func-name-check is found.
3255 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3257 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3258 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3260 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3262 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3263 the way guile-1.3.4 worked, but #if 0 out the version using
3264 SCM_VALIDATE_INUM_COPY for stricter testing.
3266 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3268 * guile-doc-snarf.in: Use new $fullfilename for running
3269 guile-func-name-check, and put "$fullfilename" and "$filename" in
3270 quotes at uses to make sure re-splitting on whitespace does not
3271 occur (so filenames w/ embedded whitespace would work okay, though
3272 I sure hope we never have to deal with that! :-) ). Thanks to
3273 Mikael for pointing out the source_dir != build_dir was broken.
3275 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3277 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3278 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3279 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3280 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3283 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3284 then return whether it's an open port (was validating that it was
3285 an open port -- this was a bug I introduced back in December, but
3286 my careful reading of diffs caught it).
3288 * numbers.c: Recombine the two conditional-compilation paths for
3289 all the log* primitives -- they were split based on #ifndef
3290 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3291 some bugs and inconsistencies in the two sets of implementations.
3292 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3294 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3295 SCM_VALIDATE_INUM_COPY once where it should've been used.
3297 * fluids.c (scm_internal_with_fluids): Use
3298 SCM_VALIDATE_LIST_COPYLEN.
3300 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3301 this is questionable as it relaxes type safety, but other changes
3302 were useful and all SCM_NUM2LONG's should probably be
3303 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3305 * evalext.c: line-break change on 1 line.
3307 * eval.c (nconc2last): Takes a non-empty list as its first
3308 argument, not just a list.
3310 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3312 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3314 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3315 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3318 * symbols.c (scm_sysintern0): Fixed the function name in a
3319 scm_misc_error invocation.
3321 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3322 use scm_return_first to ward off latent GC bug that Mikael caught.
3324 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3325 used before but should've been.
3327 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3329 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3330 SCM_FUNC_CAST_ARBITRARY_ARGS.
3332 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3334 * guile-func-name-check.in: Added this script to statically check
3335 #define FUNC_NAME, #undef FUNC_NAME in the source.
3337 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3338 redundant comment, semicolon; caught by new guile-func-name-check
3341 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3342 Caught by new guile-func-name-check-script.
3344 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3346 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3347 guile-func-name-check.
3349 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3352 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3354 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3355 port function take const void*, not void*.
3357 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3359 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3360 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3361 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3362 consistency with the other macros dealing with immediate
3363 characters. (Similar to INT -> INUM change a week or so ago).
3365 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3367 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3368 net_db.c, read.c, socket.c: Update error messages to use ~A for
3369 %s, ~S for %S to work with new `simple-format' format and be
3370 standardized better.
3372 * print.h, print.c (scm_simple_format): Added `simple-format'
3373 primitive. It's the old scm_display_error, with ARGS now a rest
3374 parameter, and the destination first instead of last (and a couple
3375 new capabilities inspired by `format' -- #t as destination means
3376 current-output-port, #f means return the formatted text as a
3379 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3381 * backtrace.c (scm_display_error_message): Rewrote to use
3382 scm_simple_format() procedure.
3384 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3386 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3388 Finally applied the libltdl patch from Thomas Tanner, with slight
3391 * DYNAMIC-LINKING: Removed because it is obsolete.
3392 * dynl.c: Use ANSI prototypes.
3393 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3394 * scmconfig.h.in: Do not change, as it is automatically generated.
3396 1999-07-25 Thomas Tanner <tanner@ffii.org>
3398 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3400 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3401 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3403 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3404 * guile.c: register preloaded modules
3405 * scmconfig.h.in: remove obsolete symbols
3407 2000-01-09 Gary Houston <ghouston@arglist.com>
3409 * These changes should make it unnecessary to call tzset from
3410 Scheme after modifying the TZ environment variable, even if the
3411 system date facilities cache the value.
3412 * stime.c (setzone, scm_localtime): added comments.
3413 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3414 (setzone): don't call tzset.
3415 (restorezone): call tzset only if HAVE_TZSET is defined.
3416 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3417 doc string to indicate that this procedure isn't likely to do
3419 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3420 LOCALTIME_CACHE is defined.
3422 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3424 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3426 2000-01-09 Gary Houston <ghouston@arglist.com>
3428 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3429 scm_lookupcar1: throw an error with key 'unbound-variable instead
3430 of 'misc-error when an unbound variable is encountered.
3432 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3433 scm_symlink, scm_readlink, scm_lstat),
3434 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3435 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3437 simpos.c (scm_system),
3438 stime.c (scm_times, scm_strptime):
3439 move the HAVE_XXX feature tests out of the procedure bodies.
3440 don't use SCM_SYSMISSING.
3441 scm_validate.h (SCM_SYSMISSING): removed.
3442 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3443 see ChangeLog entry for 1999-12-28.
3445 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3447 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3449 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3451 * backtrace.c: Fix spelling typo in a comment.
3453 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3454 text. Reformatted some of the expansions.
3456 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3458 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3459 report the position of the argument.
3461 * error.h, error.c (scm_out_of_range_pos): Added this function to
3462 take extra "pos" argument, the position number of the errant
3465 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3467 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3468 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3469 prefers that and I'm reasonably indifferent.
3471 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3473 * snarf.h: Factor out differences between C++ and non-C++ into
3474 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3475 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3476 Mikael's macros, below, but changed names and SCM_SNARFING no
3477 longer expands to include %%% -- that must appear in the argument
3478 so that the token appears at the call-site as a reminder).
3480 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3482 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3483 snarf macro definitions.
3485 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3487 * chars.c (scm_integer_to_char): Use Greg's nice
3488 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3491 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3493 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3495 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3497 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3498 instead of GUILE_PROC.
3500 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3502 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3503 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3506 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3508 * scm_validate.h: Remove some redundant NIMP tests.
3510 * alist.c: minimize scope of the tmp variables, and initialize
3511 them when declared. The strange SCM_NIMP tests are replaced by
3512 SCM_CONSP tests that more closely reflect the intended semantics.
3513 However, we don't get a performance penalty here, because the
3514 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3515 extremely ugly use of ASRTGO macros was removed: The calls to
3516 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3517 label parameter that only exists when SCM_RECKLESS is not defined.
3518 This works, because ASRTGO itself is defined in a way that it only
3519 makes use of the label parameter if SCM_RECKLESS is not defined
3520 (shudder!). Does guile make at all use of the possibility to
3521 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3522 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3523 we now only get one test.
3525 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3526 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3527 some variables in `list?'. Fix `reverse' and `reverse!'
3528 primitives to handle improper lists better.
3530 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3532 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3533 macros and SCM_DEFINE macros to match GNU coding standards.
3535 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3537 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3539 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3541 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3542 better consistency with the names of other SCM_VALIDATE_ macros
3543 and better conformance to guile naming policy.
3545 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3547 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3548 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3549 it's not the actual name of the formal).
3551 * guile-snarf.awk.in: Do argument/number mismatch checking and
3552 print warnings in an Emacs compile-mode parseable format.
3554 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3555 SCM_OUTOFRANGE as 3rd argument.
3557 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3559 * __scm.h: Do not #define SCM_ARG* when snarfing;
3560 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3561 the former (using the number) requires the argument to match the
3562 formal in the current argument snarfing check.
3564 * snarf.h: Give new definition of SCM_ASSERT when in
3565 snarfing mode to output a lexically-identifiable sequence that the
3566 guile-snarf.awk script uses to verify argument/position matching.
3568 * ramap.c: Remove extraneous #undef FUNC_NAME.
3570 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3572 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3573 current version of the same functionality; it writes the .x output
3574 to stdout instead of directly into the file.
3576 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3578 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3579 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3580 redundant with the safer macros. Patch from Dirk Hermann applied
3581 by hand. Thanks Dirk!
3583 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3586 * ramap.c: whitespace change.
3588 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3590 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3591 removals from Dirk Hermann.
3593 * alist.c: Rename formals to match the parameter names in the
3594 documentation, updates to documentation. Thanks Dirk Hermann!
3596 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3598 * eval.c (SCM_CEVAL): Reverse order of
3599 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3600 (Thanks to Brad Knotwell.)
3602 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3604 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3607 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3610 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3612 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3613 SCM_NIMP tests that were redundant are now eliminated. Patches
3614 from Dirk Hermann applied by hand.
